This nebula complex is about 1500 light years from Earth, is located just below Alnitak, the star furthest left on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. Components of this image include dark nebula Barnard 33; the vast red emission nebula IC 434 in the background illuminated by Sigma Orionis; reflection nebula NGC 2023 below the Horsehead; and NGC 2024 (Flame Nebula).

NGC 2023 is one of the brightest sources of fluorescent molecular hydrogen in the sky and is a cavity in the Orion Molecular Cloud 4 light years wide - one of the largest reflection nebluae.

NGC 2024 is an emission nebula and stellar nursery located about 1,500 light years from our solar system. The nebula is a region of star formation that is in the process of forming a star cluster.
